Check Engine Light Due to Air Fuel Sensor Fault on Honda Civic

Problem Description and Possible Solution

The air/fuel sensor, located in the exhaust system, may be damaged by moisture in the exhaust resulting in illumination of the Check Engine Light. Replacing the damaged air/fuel sensor and updating the powertrain control module (PCM) software should correct this concern.

Engine light came on. Honda service diagnosed as Air Fuel Sensor gone bad. Testing, part and service cost $413.00. Really only problem after all these miles.
